Product Description

The EX-4000 is a high-efficiency professional power amplifier, with two independent channels, each capable of delivering 720 watts into 8-ohm loads, 1100 watts into four ohms, and 1400 watts into two ohms. Semi-toroidal power transformers, which reduce the unit's weight, are mounted in each front corner, as close as possible to the rack ears and rails. The amplifier occupies three rack spaces, weights 64 lbs, and requires a rack depth of 18" to clear the rear support ears. The rear panel is 16.9" behind the front mounting plane, so an extra rack depth allowance (i.e., more than 18") will be needed to clear the XLR or Speakon connections. The built-in fan cooling takes air in the rear, exhausting through the front vents. Due to the flow-through cooling, amplifiers may be racked with zero clearance in between, which also helps support the weight.
